This study was conducted to develop a group counseling program to solve the problem of maladjustment of military personnel and to verify the effectiveness of the program. The 12 session CBT and ACT program for military soldiers experiencing emotional and behavioral problems was developed and the effectiveness was verified by conducting a program once a week for soldiers in the army units based in South Chungcheong Province. Adult Self Report scale(ASR) was implemented for pre-post test and analysis, and descriptive statistical analysis, cross-analysis, paired sample t-test, and independent sample t-test were performed to analyze the results. The results indicated are as follows: First, the preliminary homogeneity test between groups showed that the two groups had homogeneous demographic characteristics and the characteristics of the variables. Second, as a result of the pre-post test verification, both CBT and ACT groups showed significant changes in problem behavior totals, internalizations, and externalizations. Third, there was no difference between the pre-post-examination of the CBT group and the ACT group. This study is meaningful in that it was involved in the maladjustment problem within the military unit, and compared the effectiveness between the two theories, and proposed the study of control groups and further studies on more diverse and diverse subjects that were not implemented under the circumstances of the unit.

Subjects were 28 men and women with a round shoulder posture, and they were randomly assigned to a mat pilates group (MPG, n=14) and a Kinesio taping group (KTG, n=14). Each group performed the intervention for 4 weeks, and the distance from the ground to the acromion(DGA) and muscle characteristics (F: Frequency; S: Stiffness; D: Decrement) were measured before and after the intervention. Independent T-test was performed for the difference in the amount of change between groups, and the paired-sample T-test was performed for the difference between pre-post values within the group. Statistical significance level was set as 𝛼=.05. As a result of measuring the change in DGA in both groups, it was significantly decreased in MPG (p<.05). As a result of measuring the change in muscle characteristics of the two groups, the change in F in TL was significantly increased in MPG (p<.05), there was no change in TG, and the amount of change in MPG was larger in the amount of change between the two groups. appeared (p<.05). The change in S was significantly increased in MPG (p<.05). Therefore, the mat pilates conducted in this study is considered to be an effective intervention for improving the round shoulder posture and changing the muscle characteristics than kinesio taping.

Interleukin-17A (IL-17A) is a pro-inflammatory cytokine mainly derived from T helper 17 cells and is known to be involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). Cigarette smoke (CS) has been considered as a primary risk factor of COPD. However, the interaction between CS and IL-17A and the underlying molecular mechanisms have not been clarified. In the current study, we investigated the effects of cigarette smoke extract (CSE) on IL-17A-induced IL-8 production in human bronchial epithelial cells, and sought to identify the underlying molecular mechanisms. IL-8 production was significantly enhanced following treatment with both IL-17A and CSE, while treatment with either IL-17A or CSE alone caused only a slight increase in IL-8 production. CSE increased the transcription of IL-17RA/RC and surface membrane expression of IL-17R, which was suppressed by an inhibitor of the phosphoinositide 3-kinase (PI3K)/Akt pathway (LY294002). CSE caused inactivation of glycogen synthase $kinase-3{\beta}$ ($GSK-3{\beta}$) via the PI3K/Akt pathway. Blockade of $GSK-3{\beta}$ inactivation by overexpression of constitutively active $GSK-3{\beta}$ (S9A) completely suppressed the CSE-induced up-regulation of IL-17R expression and the CSE-induced enhancement of IL-8 secretion. In conclusion, inactivation of $GSK-3{\beta}$ via the PI3K/Akt pathway mediates CSE-induced up-regulation of IL-17R, which contributes to the enhancement of IL-17A-induced IL-8 production.

Purpose of the present study was to find the optimal culture conditions for the maturation and fertilization of immature oocytes by the use human body fluids and gonadotropins (Gn) in the mouse model. Cumulus-enclosed mouse immature oocytes were incubated in the medium containing various human body fluids with or without Gn in vitro, and examined to confirm nuclear maturation (NM) and fertilization. Female ICR mice were stimulated with 7.5 IU pregnant mares' serum gonadotropin (PMSG). Cumulus-enclosed immature oocytes were isolated at 48-52 hr post PMSG injection and cultured in TCM 199 supplemented with various concentrations (20, 50, and 70%) of human body fluids such as fetal cord serum (hCS), follicular fluid (hFF), peritoneal fluid (hPF) and amniotic fluid (hAF) in the presence or absence of 10 IU/ml PMSG and 10 IU/ml human chorionic gonadotropin (hCG) for 18 hr. Fetal calf serum (FCS) was used as a control for the supplements. Matured oocytes were fertilized with sperm collected from the epididymis of male mice. Fertilization was conducted in T6 medium containing 15 mgl ml bovine serum albumin, and confirmed at 6 hr post-insemination. Evaluation of nucler maturation and fertilization was carried out by rapid staining using fuchin. There was no significant difference between the effects of human body fluids and FCS supplements on nuclear maturation of cumulus enclosed mouse immature oocytes. When maturation medium was supplemented with 20% hPF or 20% hAF, fertilization rates were significantly (P<0.01) lower than that of 20% FCS, hCS and hFF groups. However, higher concentrations of body fluids during IVM were not more beneficial on fertilizability of oocytes. The addition of Gn significantly increased the fertilization rates in hPF and hAF groups (hPF without Gn; 51.5%, compared with 85.1% for addition of Gn, and hAF without Gn; 30.1% compared with 85.8% for addition of Gn) at 20% concentration. These results suggest that human body fluids at 20% concentration and gonadotropins can be used as supplements for the maturation of mouse immature oocytes in vitro. When gonadotropins supplemented with the human body fluids in the maturation medium, fertilizability of mouse immature oocytes was increased in hPF and hAF groups. These results can be applied to maturation of human immature oocytes in vitro.
